1. A transversal filter allrate equalizer for equalizing an intermediate frequency input signal, said equalizer comprising:

  • a signal divider coupled to receive the intermediate frequency input signal;

    a transversal filter comprising;

    a plurality of delay lines coupled to signal divider for producing time-shifted replicas of the intermediate frequency input signal; and

    a plurality of multiplying circuits respectively coupled to the delay lines for weighting the time-shifted replicas of the input signal by complex numbers; and

    a signal combiner coupled to the plurality of multiplying circuits for recombining the time-shifted and weighted replicas of the input signal to produce an equalized output signal.
